Even in your example, and assuming that the only feature that the enterprise plan offers is SSO, that's not even close to a 12400% increase, that's a 1147% increase.
My point was that saying the minimum order is 125 seats for enterprise, and so claiming that the price for a single seat is increase by 12400% is being deceptive.
If you buy a six-pack of beer, you don't say "This is terrible! I only wanted one beer and this six-pack is a 500% increase in price!". If you only want one beer, you just buy the single beer and leave the six-pack on the shelf.
If there is an option to buy a single beer on the shelf, sure. But in this case there is no such option.
Imagine you _really_ wanted to try Foobar beer. So you get to beer distributor, and you find out that while each bottle is just $5, the minimum order is a crate of 144 bottles and they give no samples.
In this case, you might say: "Yeah, I really wanted to try that beer but there is no way I am paying $720 for that". It's exactly the same here.
(re 1147% vs 12400% - sure, maybe you could argue you should not look at a single license, but rather at a pack of 5 or 10 licenses... but this does not change numbers much for Coursera, it's still huge increase.)
